CASEMENT-WIN'DOW ATTACHMENT.

Specification of Letters Patent. Patented Apr. 15, 1919- Application filed September 9, 1918. Serial No. 253,259.

To all whom it may concern:

Be it known that I, ALBERT H. CARRIER, a citizen of the United States, residing at Asheville, in the county of Buncombe and State of North Carolina, have invented new and useful Improvements in Casement- Window Attachments, of which the following is a specification.

This invention relates to casement window attachments, and the primary object of the invention is to provide means cooperating with a casement window frame and sash and readily actuated for positively opening and closing the sash and for holding the sash in fixed open adjustment at various degrees for ventilation, and also to permit the sash to be turned and shifted for convenience in cleaning the outer side of the glass from the inner side of the frame and without requiring a person to occupy an uncomfortable or a dangerous position while performing the cleaning operation. A further object of the invention is to provide an at tachment of the class Specified adapted to be readily applied to casement windows, particularly such form of windows now in use, without requiring reorganization of the easement window frames and sash and by simply cutting away, boring and grooving adjacent lower and upper portions of the sash and frame to receive the cooperating components of the attachment which as a while is comparatively simple in construction and easily assembled.

With these and other objects and advantages in view, the invention consists in the preferred construction and arrangement of parts which will be more fully hereinafter described and claimed.

In the drawings:

Figure 1 is a horizontal section through a casement frame and portion of the sash therefor, the sash being broken away and showing the improved attachment in top plan, the actuating lever being broken off.

Fig. 2 is a similar view showing a portion of the sash open in full lines and shifted in dotted lines to render the outer side accessible, the components of the attachment being shown in positions corresponding to the adjustment of the sash.

Fig. 3 is a transverse vertical section taken in the plane of the line 3, 3, Fig. 1, the frame and sash being broken through.

F g.- 4 is a transverse vertical section slot, the segmental slot taken in the plane of the line 4, 4, Fig. 1, the sash being only partially shown.

Fig. 5 is an outside elevation of a portion of a casement frame and sash, the latter being broken through, showing the improved attachment applied to the lower and upper portions thereof.

Fig. 6 is a longitudinal vertical section taken in the plane of the line 6, 6, Fig. 2, shofiving only a portion of the frame and sas The numeral 5 designates a casement window frame of the usual structure and embodying the usual sill organization 6 and head 7 with the usual casement sash 8 mounted therein and in the present instance provided with the improved attachment whereby the sash may be swung outwardly and inwardly and disposed in such angle or position that the outer side of the glass 9 may be easily reached for cleaning purposes. The attachment is operative to adjust the sash at different angles for ventilating purposes or to'entirely close the same. The parts of the attachment comprise essentially a guide plate 10 fixed to the sill 6 and provided with an inner securing bar or member 11 disposed in a horizontal seat 12 formed by cutting out a portion of the sill as clearly illustrated by Fig. 3. The guide plate 10 at the end adjacent to the side of the frame is projected outwardly a suitable distance to form an extension 13 and has a brace strap or bracket arm 14 depending therefrom'and bent inwardly. and secured to the outer face of the sill 6 to stabilize the extension 13 and also to reinforce the latter sufficiently to sustain the weight of the sash. adjacent to the extension 13 has an elevated fixed toothed segment 15. The guide plate is formed with a longitudinally straight slot 16 parallel with the casement sash 9 when the latter is closed and also with a segmentalslot 17 which merges into the straight 17 being projected outwardly in the extension 13 and struck from the same center as, but with a longer radius than the toothed segment 15. The guide slots 16 and 17 have overhanging shouldered walls 18 as clearly shown by dotted and full lines in Figs 1, 2, 3 and 4. The guide plate 10 also has an innerupwardly projecting bead 19 along the inner edge of the securing strip or member 11, the latter continui g into an arcuate enlargement 20 The guide plate 10 having a pin 21 rising therefrom. The bead 19 prevents leakage of water between the sill and bottom rail of the sash 8 at the point where the guide plate is applied to the sill,

it being understood that the remaining part of the lower rail of -the sash 8 will snugly fit relatively to the sill and stool 22 in the usual manner When the said sash is closed. The guide plate is also provided with a switch consisting of a head 23 fulcrumed on the strip or member 11 and havinga reduced arm 24 to close communication between the straight slot 16 and the arcuate or segmental slot 17, the one edge 25 of the arm 24 having the same curvature as the inner wall of the slot 17 so as to continue the slot rearwardly the requisite distance for the operation of the mechanism which will be presently described when the said switch is closed or arm 24 stands across the point of intersection of the slot 16 with the slot 17. The slot 17 continues inwardly through the plate 10 a short distance past the inner side wall of the slot 16 so as to permit a complete closure of the sash 8. The guide plate with the structural features herein'before specified may be readily applied to the frame sill 6 by a simple operation and all the parts or components thereof are properly positioned at one operation when the plate as a whole is disposed on the sill.

The lower rail of the sash 8 is bored, as at 26, a comparatively short distance upwardly thereinto adjacent to the outer side, and this bore is cut throughthe outer side by suitable means as for instance by chiseling, and

at the base of the bore a recess 27 is also out in the outer portion of the lower side of the rail. A socket 28 is fitted in the bore 6 and has a lower flange 29 secured in the recess 27, the socket also embodying an outer vertical closure plate 30 having a horizontal flange 31 intersecting and integrally forming a part thereof at the lower end, said flange being given an arcuate form with the center of the socket as the radius and constructed with segmental teeth 32 to mesh with the teeth of the segment 15, the flange 31 providing toothed means carried by the sash to cooperate with the segment 15 to effect a regular turning and outwardly projecting movement of thesash 8. Projecting upwardly into the socket 28 is a stud or dowel 33 having a lower flanged head 34 which is held in engagement with and takes under the shouldered walls 18 of the slots 16 and 17, the stud or dowel 33 being secured in the socket by a screw or other fastening means 35 as clearly shoWn by Fig. 3. Surrounding the portion of the stud or dowel pin 33 depending below the lower terminal of the socket is a roller '36 which is of such diameter relatively to the width of each of the slots 16 and 17 as to anti-frictionally en gage the side Walls of said slots with a free sliding movement. As shown by F 3, the lower terminal of the socket is in the same plane as the upper terminal of' the pin 21, and shiftably mounted on this pin is a lever or hand-actuating bar 37 which projects through the inner portion of the frame 5 and has an oscillating movement. The outer end of the lever or hand bar 37 is provided with a yoke-head 38 having a slot 39 opening through one side thereof and of such dimensions as to snugly engage the roller 36 and the stud or dowel 33 below the socket 28 by means of the roller for'shifting and operating the sash in opening and closing movements thereof during the time that the lower portion of the stud or dowel pin 33 and the said roller 36 are in engagement with the slot 17. A washer 38' is-around the portion of the roller 36 close to the yoke head 38 to hold the latter in proper workingposition, the said washer projecting over the slots of the guide plate 10. The lever or hand bar 37 is formed with a series of alternately intersecting angular slots 40 eX- tending lengthwise thereof a suitable distance, said slots terminating in transversely straight members 41 which provide stops or locking portions for the slots, and with these slots the pin 21 cooperates and is in continual registration. By the formation of these slots 40 with the end stop portions 41 thereof, the lever or hand bar 37 is rendered slid'able to compensate for the outward movement of'the sash during the turning operation of the latter, and when the switch has been shifted outwardly the desired distance through the medium of the lever or hand bar 37, it may belocked in any degree of open, position desired by moving the lever or hand bar toward the pin 21 to engage either one of thestraight end portions 41 of the intersecting slots 40. These slots alternately vary as to their angle in regular formation, and in the operation of the lever or hand bar 37 it is oscillated regularly by simply pushing outwardly thereon after the pin 21 has been disengaged from any one of the locking slots 41.

' The upper or top rail of the sash 8 and the head 7 of the frame are equipped with cor responding structures, such as a guide plate 10 which isdevoid'of the securing brace or bracket 14 and whereon the segment 15 is in closer relation to the guide plate and the upper rail of the sash has a socket fitted therein with a stud or dowel having a flanged head, the socket also being provided with a flange formed as a toothed segment. There is no operating lever or hand bar 37 at the top of the sash and frame but the same form of switch comprising the head 23 andrarm 24 is used. All of the parts at the top of the sash and head of the frame operate in the same manner as the lower corresponding devices, those at the top of the sash and frame being in reverse positions as will be readily understood, and in adjusting the switch controlling communication between the slots 16 and 17 in the top guide plate a suitable rod Or other means will be used to control the same, whereas the switch in the lower sash is opened and closed manually whenever it is desired to shift a sash so as to cause the stud or dowel pin 33 and roller 36 to engage the guide slot 16. Reference characters designating the same structural features in the upper guide plate, socket, and stud or dowel pin and other accessories as those in connection with the lower rail of the sash and the sill of the frame have been applied, and as the specific construction and operation of these parts at the upper portions of the sash and frame are the same as at the lower portions of the sash and frame, further detail description will not be given relative thereto.

The operation of the sash through the medium of the mechanism described may be briefly stated as follows: When the sash is in the closed position, the pin 21 will be in the outermost straight terminal slot 41 of the lever or hand bar 37 the sash then being locked closed, and at this time the last tooth of the series of teeth 32 of the flange 31 adj acent to the one end of each sash rail will engage between the innermost two teeth of the segments at the lower and upper portions of the frame. When it is desired to open the sash, the lever or hand bar 37 is shifted laterally to disengage the pin 21 from the outer straight terminal locking slot with which it has been in engagement, and by pushing outwardly on the said lever or hand bar the sash will be correspondingly moved outwardly with a combined sliding and turning action'owing to the movement of the roller-engaged stud or dowel 33 in the slot 17 and the rotation set up by the inner engaging segments on the window frame and sash, and such outward removing and rotating operation of the sash will ensue until the outer limit of the slot 17 is reached when the sash will be turned completely around,

I with the inner side thereof outermost, as indicated by Fig. 2. As hereinbefore explained, the sash may be stopped at any point during its adjustment as may be desired for ventilating purposes instead of being fully open, and it will be seen that the attachment forms a movable or adjustable hinge joint for the sash and said attachment also at the same time serves as a locking means for securing the sash at any adjustment desired or to hold the same in closed position to resist opening thereof from the exterior. The sash may also be turned for convenience in cleaning the outer side thereof without requiring an operator to assume an inconvenient or dangerous position in the window frame, and to accomplish thls result the switch arm 24 is turned or thrown inwardly, as shown by dotted lines in Fig. 1 and in full lines by Fig. 2, to open communication between the slots 17 and 16, the arm, as hereinbefore explained, being curved on its outer edge, as at 25, to regularly continue the slot 17 when the switch arm is closed, and in like manner the opposite edge 24 of the arm 24: is curved to provide an areuate wall and avoid obstruction of the movement of the roller-engaged stud or dowel pin 33 when the switch is opened. After the switch has been opened and it is desired to shift the sash into the slot 16, the lever or hand bar 37 is grasped and an inward pull exerted thereon to set up an oscillation subsequent to a clearance of the pin 21 from one of the end locking slots ll with which it has been in engagement, and the sash will thus be gradually drawn inwardly and at the same time rotating until it reaches the entrance to the slot 16 and at this time the sash is manually pushed into the slot 16 and turned as desired, and when'this manual operation ensues the roller-inclosed stud or dowel 33 is disengaged from the slot 39 in the outer yoke end or head of the lever or hand bar 37, the latter being allowed preferably to remain in the same position as when the roller-inclosed stud was disengaged therefrom, so that when the sash is moved back to normal position the said stud will again enter the slot 39. It is also preferable to lndicate on the teeth of the inner meshing segment by arrows or other devices, as at 12 and 43, the exact teeth that should be registered when the sash is brought back into normal position with the roller-inclosed stud in the slot 17 and also in the slot 39 of the yoke of the lever or hand'bar'37 so that by continued operation of the lever or hand bar inwardly, the sash may be closed through an effectual actuation of the segments. It will be understood that when the sash is brought from the dotted position shown in Fig. 2 back into engaging position relatively to the slot 17, sufficient clearance or movement of the roller-inclosedor engaged stud or dowel in 33 outwardly in the slot 39 will ensue to permit the switch arm 2 1 to be turned into closed position as shown by Fig. 1. As hereinbefore indicated, when the lower switch arm 24: is opened, the upper similar arm will also be opened and, likewise, both arms will be closed when changing the engagement of the sash from the slot 16 into the slot 17.

i It is proposed to form the several parts of the attachment of thin metal, and as heretofore indicated it may be readily applied to casement windows now in use or which have been already erected with very little trouble and at a comparatively small expense to adapt the attachment to various sizes of casement window sash and frames, and it reach the outer side thereof.
